Future Earth is obliterated by nuclear war and is no longer inhabitable by any life forms. Therefore the remaining humans leave to the only planet similar to Earth in the galaxy, which is Mort.
Mort is inhabited by man-eating bacteria, so they create a field around humans. But one day, the field is breached!
The buildings are being infected, and people are dying. But one man Eugene is not afraid as he may know how to fix this issue.
While Eugene is off to find a fix for this bacteria, people in hazmat suits try to clean it up, but they quickly find out it is invincible to anything they throw at it, and can easily break down metal.
Eugene is a man that knows all the secrets of the land and knows of a portal to extremely developed worlds that can whip up a cure to this issue.
Eugene quickly comes back and terminates the bacteria before it kills too many people, and takes over the whole planet.
